The efficacy of an extended theory of planned behavior was evaluated in the young drivers’ (N=800) speeding behavior and intention to speed. The results show that young drivers’ speeding behavior appears to be affected by perceived behavioral control, past behavior, personal norms, intention to speed, affective and evaluative attitude towards compliance with speed limit, and social support. It also found that the impact of personal norms is greater in the intention to speed. Furthermore, the effect of socio-economic characteristics and the vehicle usage such as gender, age, income level, university type, and location of university etc. were significant factors to report that young drivers are more likely to be speeding offenders. Interestingly, racing movies and racing also make important predictors to influence drivers to drive exceeding the speed limit.
